I believe that one should know about the law of attraction before they go watching a bunch of doom and gloom educational videos. For example, once I had fully grasped the law of attraction it did not make me near as frustrated as I would have been, if i was to go watch loose change, an alex jones film or zeitgeist.
Of all the eye openers I think the best one is "Esoteric Agenda" on google video. It educates you about the fact that we are controlled to a T, but then shows you that we are in control of our reality and how we can overcome this stranglehold if we pay close attention to our consciousness.
Here is the link if anyone has not seen it.
